XMI is XMI. There were some minor revisions for the VAX9000 (my fault),
but they wouldn't effect SimH.

XMI was used in two modes; in the 6000 as a system bus; in the 9000 as
an I/O bus (the XMIs hang off an adapter from the system's switch). As
an I/O bus, each XMI is mapped into the physical address space. Sort of
like Unibus on 780. Note that busses nest; XMI can have XBI to produce
BI busses.
I don't recall how XMI was used on the 7000.
